Two of the gun turrets from the battleship Bayern. Straight to the bottom of the first turret and saw the ball bearings. Swam on round the other turret. Returned to the first turret and made several circuits, seeing sun stars, edible crab and a few congers.
Met up with Tony at the bottom of the shot line and we made our way to 6m for 13min of stops and 5min safety stop.
